Added a sinx4 benchmark - for computing 4 float32 sin() values in parallel
Merge branch 'master' of https://github.com/johnmccutchan/ecmascript_simd
Remove use of "new float32x4" and "new uint32x4"
Move constructors into SIMD module
Added new operations
Uint32x4 -> Int32x4 for Dart mandelbrot benchmark
Add Dart port of aobench and sinx4 by Zachary Anderson
Updated the sinx4.js benchmark and added it to run.js
Add averageFloat64x2.js
Add averageFloat64.dart
Added SIMD.float64x2 (abs, neg, add, sub, mul, div, clamp, min, max, scale, sqrt, withX, withY, SIMD.float32x4.toFloat64x2)
Added reciprocal, reciprocalSqrt, shuffle, shuffleMix, comparison, and select operators to SIMD.float64x2
Changed conversion operators from SIMD.XXX.toYYY() to SIMD.YYY.fromXXX(), added 'select' operator for all types, added/updated tests
Use object properties instead of typed array as storage in polyfill
Fix float64x2.clamp implementation and add test case for it.
